Modernization of servo-hydraulic testing machines

The modular RetroLine modernization packages for servo-hydraulic testing systems can easily be tailored to your individual needs and testing requirements. Modernization of your testing machine usually includes renewal of the measurement and control electronics and the testing software. If necessary your modernization can involve a complete solution package with replacement and re-engineering of the hydraulic components Areas of application range from materials characterization on single-axis materials testing machines to complex component-testing on multiaxial testing systems, for example simulation tests.

Additional sensors, specimen grips and test fixtures from the comprehensive Zwick accessory range can be retrofitted.

Solution using testControl II

Modernization with testControl II measurement and control electronics is an ideal match for single-channel testing machines. testControl II is the optimum control system for standard tests or determination of material properties and impresses through its unique capabilities in dynamic loading (fatigue tests), component testing and low-cycle fatigue.

The combination of testControl II plus intelligent testXpert Research software represents a high-powered team when it comes to precise control and intuitive operation. Modular software design handles standardized tests to ISO/DIN or ASTM standards and specific tests with equal facility.

Modernization with Control Cube digital measurement and control electronics is employed for multichannel and/or complex servo-hydraulic testing systems. The Control Cube servo controller is also the optimum modernization solution where frequent test-arrangement changes are involved. As well as established standard tests, Control Cube technology is also used for modernizations in conjunction with component and assembly testing. The system’s modularity and flexibility make it ideal for multi-channel applications and simulation tests.

Along with the Control Cube servo controller you will receive the current version of the Cubus testing software. Cubus features a simple, well-structured, innovative user interface, while its flexibility and modular design allow system configurations for testing requirements ranging from the simple to the complex.

At its factory in Gardone val Trompia, Italy, Radaelli produces steel wire ropes for a wide range of uses. These include offshore applications, construction machinery, ropeways and cableways and bridge-building. The growing demand for wire ropes with ever-higher load capacity is also placing an increasing burden on quality assurance. After modernization by Zwick the testing machine can now perform tensile tests up to 3,000kN.
